In the specific embodiment of. the invention illustrated in Figs. 1 to 6, inclusive, a shell 1 isformed centrally with an upstandingeye 2 by means of which it maybe suspended from the ceiling. This shell is connected to a bottom plate 3 by a series ofbraces 4 whichare adapted to be shaped so asto form asuitable ornamentaldesign. For convenience in assembling these parts, the shell .1 is formed with a series of equally spaced radial slots 5, corresponding in-number to the number of braces 4. The ends ofthese slots di- 1928.

verge inwardlyand the upper ;end of .each bracei is formedwith a toe badapted to be 1nsertedinthe slot and having a forwardly projecting point 7 adapted to engage in locking relation with the outer end of ,the slot when the brace is swung inwardly to the position shown in Fig. 3. The lower face of the shell 1 is curved downwardly to -form an abutment r01 the opposed faces Off the legs 4 andito hold themin locked position.

The bottom plate3 isformedwith a series ofslots .8 adapted to receivethe toes9 formed at the lower ends of the braces 4C. Each toe 9 is formed with a notch 10 whichis adapted to engagathe outer edge of tlleslot 8.

After the shell 1, brace landplate Shave been placed in assembled relation, a spider llis securedtoithe plate 3bymeans of screws 12, the plate being formed with key hole slots 13;for receivin the screws, in order to i'acilitate the assem ling operation. The spider 11 is formed With upstanding lugs 14. adapted to engage behind the toes 9 aiidlockthelatter inthe jslotsfi.

flhe spider 11 is forniedwith a series of radiallyextending 4 arms 15 which have, studs 16 or similar .rneans at their outer L ends for attaching electric light socketsthereto. Each arm ,formed with a i channel 17 which extends inwardly beneath the plate 3] and is adapted ,to receive the wiring. .A Qlip .18 ma een i h i tom of th c nne 7, as'lshm n in Fig. 6 ,3501. convenience in attach- .ing the wire to the arm.

This embodiment comprises a shell B having a central Qflfor suspend- .the same from the ceiling- .Aibottom plate. 3 is connected to the: shell 1 by nieans of braces 43*. i

flhe shell l? is formed i with lotsb? adapted toreceive toes 6 formed at t s upper ends of the respective braces and having lips 7 adapted toengage over theedges of theslots. In this form; however, the ldwcr ends of the braces are swung outwardly into locking position instead of inwardly.

The bottom plate 3"* is formed with peripheral radial slots 8 adapted toreceive toes 9 formed at the lower ends of the braces 4. these toes being formed with notches 1O adapted to engage about the inner edges of the slots 8*.

The bottom plate 3 is locked in assembled relation by means of a spider 11 which is secured to the plate 3 by means of a bolt 12. The spider is formed with shoulders" 14 adapted to engage behind the toes 9 to lock the latter in position.

The spider 11 is formed with radial arms 15 terminatingin sockets 16" adapted to receive the electric lamps. The arms 15 are formedwith channels 17 to receive the wires.

From the foregoing description it will be seen that in either of the forms herein shown and described the spider and bottom plate are supported directly from the shell by the braces without any central connecting rod or bar. The mere addition of the spider to the plate serves automatically to lock the braces both to the shell and to the plate so that no other means is required to support either the plate or the spider.

, It will also be noted that the fixture is so constructed and assembled that the various parts may be easilycast or stamped and may be conveniently made in a great variety of attractive and ornamental designs. By such construction, both the manufacture and the assembly of the fixtures are greatly facilitated and their commercial value is increased.

It will also be understood that the distinctive features of the invention may be used in a great many different ways and their form and arrangement considerably modified without any material departure from the scope of the invention as claimed.
